What causes a burnt taste in espresso from Mr. Coffee?
The burnt taste in your espresso can primarily be attributed to overheating the coffee grounds during the brewing process. When the water temperature exceeds the ideal range of 190°F to 205°F (88°C to 96°C), it can extract bitter compounds from the coffee, leading to an unpleasant flavor profile. Additionally, if the brewing time is extended beyond the recommended duration, it can further intensify the burnt taste as the coffee continues to extract even after it has been properly brewed.
Another common reason for burnt flavor is the quality of the coffee beans used. If the beans are over-roasted, they may already carry a burnt taste, which will carry over into your brewed espresso. It’s essential to use fresh, high-quality beans that have been roasted to your preference to prevent this issue. Ensuring proper storage of your coffee beans away from heat, light, and moisture can also help maintain their flavor integrity.
